    The conversion of water to hydrogen using electricity has about 20% efficiency. There is no advantage over electric vehicles ever since batteries have become compact enough to make battery-powered electric vehicles feasible.

      There are some advantages, batteries require more pollution to be created and have a larger environmental impact if not dealt with properly. A hydrogen car has the potential to be 100% clean. That being said I don’t think it’s that big of an advantage considering some of the difficulties involved in it.

      What about batteries’ explosive potential & a lifespan shorter than the metal cage it propels?

      Hydrogen vehicles would be superior to that.

        Batteries don’t really explode, they combust. The metal cage usually outlives its ICE engine as well.

        Hydrogen fuel cell vehicles either need extreme insulation to keep the fuel cool, otherwise it has to vent some fuel or risk exloding, or extremely strong pressure vessels in the car to maintain the hydrogen in a liquid form. A metal cylinder constantly expanding and contracting while simutaneously seeing extreme temperature changes is going to wear out much faster than the frame of the vehicle.

        The Hindenburg was battery powered, oh, the humanity.

        Guess what element on the periodic table causes batteries to explode? hint: not mentadent.

        Compared to a literal TANK OF HYDROGEN. Hmmmm…

        a lifespan shorter than the metal cage it propels?

        Yeah, there aren’t any cars in the junkyard that were scrapped because they threw threw a rod or chewed up their transmission…

        Wow. Just, wow.
